### Research

I'm currently working on a method to estimate M dwarf ages combining different age indicators in a Bayesian framework. The age indicators I'm combining are Hα emission, 3D velocities, position in the color-magnitude diagram (CMD) and rotation period.

During my Ph.D. (2016-2021) I was part of the BDNYC research group where I worked with my advisors Prof. Kelle Cruz and Dr. Jackie Faherty. During this time I worked on the projects described below. My thesis defense was on July 16th 2021 and the recording is available online.

#### Age-relations for M dwarfs in the CMD

I collected a sample of 74,216 M and L dwarfs with Hα measurments and Gaia DR2 photometry, parallaxes and proper motions. Using this sample I found relations between age indicators and the position in the CMD. Find more about the sample in **my paper Kiman et al. 2019**. And reproduce this CMD and more with this jupyter notebook.

#### Age-activity relation for M dwarfs

I characterized the Hα Age-Activity relation for M dwarfs using a sample of age-calibrators with Halpha equivalent widths from the literature. I obtained their ages from known moving groups and white dwarfs co-movers. Read **my paper Kiman et al. 2021** to learn more about this work.

#### Ages of white dwarfs

I developed an open source Python package called `wdwarfdate` to estimate white dwarf ages from an effective temperature and a surface gravity in a Bayesian framework. The paper describing the code is in prep. The source of `wdwarfdate` can be found in GitHub.
